-<h1 align=center> ECS </h1>
-
-Brenta Engine features an Entity Component System architecture. The
-ECS is a design pattern that allows you to structure your code in a
-way that is more modular and scalable.
-
-### Entities
-
-Entities are objects in the game, it's just an ID. The `entity` class
-helps you manage the entity, for example by attaching a component to
-that entity, or removing the entity from the world.
-
-```c++
-Entity e = World::new_entity();
-```
-
-### Components
-
-Components are pieces of data that are attached to an entity:
-
-```c++
-struct PhysicsComponent : Component {
-    float mass;
-    float density;
-    glm::vec3 velocity;
-    glm::vec3 acceleration;
-    
-    PhysicsComponent() = default;
-};
-
-// Somewhere
-e.add_component<PhysicsComponent>(10.0f);
-```
-
-### Systems
-
-Systems are functions that operate on entities with specific components. They
-are called at each game tick by the `World`:
-
-```c++
-struct FPSSystem : System<None>
-{
-  void run(std::vector<EntityId> _) const override
-  {
-    auto font = AssetManager::get_font("TextFont");
-    auto fps = std::to_string(Window::get_time().get_fps());
-    brenta::Text::render("FPS: " + fps,
-                         25.0f, 25.0f, 0.35f,
-                         Color::yellow(), font);
-  }
-};
-
-// To register the system
-World::register_systems<FpsSystem>();
